WordPress 6.5 “Regina” has landed, and for developers who’ve been watching the platform’s evolution closely, this release marks a genuine turning point. The Interactivity API — previously a Gutenberg experiment — is now a stable WordPress core feature, enabling reactive, stateful front-end interactions without reaching for a JavaScript framework. Combined with a redesigned font management system and a wave of new Gutenberg block capabilities, 6.5 is the most consequential WordPress release since the Gutenberg editor itself.

The Interactivity API Explained

WordPress sites have traditionally required either jQuery-era DOM manipulation or full JavaScript framework integration (React, Vue) to implement dynamic behaviors like toggling accordions, filtering results, or updating content without page reloads. The Interactivity API offers a middle path: a lightweight, server-rendered approach to reactivity that keeps your markup in PHP while enabling modern dynamic behaviors through declarative HTML attributes.

Font Library

Managing typography in WordPress has historically been painful — inconsistent font loading, plugin dependencies, and the complexity of Google Fonts privacy compliance. The new Font Library addresses all of these issues with a centralized font management system in the Site Editor that handles installation, preview, and licensing information in one place.
